Good point @muzzak. The supply charge shows up as a separate line item so I’m not too fussed.
But I see what you mean especially when we are tracking monthly / yearly totals.
As per your suggestion, I’ll change the above unit to Wh and then multiply the supply charge by 1000.
Hi Michael,
Yes that’s correct, as per the yaml standards one heading with utilities as subentries beneath indented or a reference (as I have done) to a separate file for your multiple utility entries.
Thanks,
Sean
Thank you @muzzak for this. I was stumped at first with an error but that was soon resolved with the addition of:
sensor:
- platform: time_date
display_options:
- 'time'
- 'date'
- 'date_time'
- 'date_time_utc'
- 'date_time_iso'
- 'time_date'
- 'time_utc'
- 'beat'
Cheers
Simon
Yes @simonranson, good point. I should have mentioned you need the Time and Date integration as well Time & Date - Home Assistant
Hi @muzzak @aksvenk I’m trying to get this code working but the daily cost is zero.
Please are you able to share to final code for the once off daily “spike” - i prefer this option than the cost calculation over the entire day.
Also what “static price” do you use in the Supply Charge for the Grid Consumption dashboard using this approach?
I find all the solutions above a bit more complicated than they need to be. Here’s what I did:
template:
- trigger: # rate-limit the template a bit, which would otherwise re-calculate every minute
- platform: time_pattern
hours: "*" # calculate hourly should be fine
sensor:
# Increases every day by 1W to fake a daily supply charge in energy dashboard.
- state: >-
{{ 0.001 * (now() - "2022-09-26" | as_datetime | as_local).days }}
unit_of_measurement: kWh
state_class: total_increasing
device_class: energy
unique_id: CHANGE_ME_TO_ANYTHING_JUST_MAKE_IT_UNIQUE
name: "Daily supply charge"
Just set the date "2022-09-26" to the day or day before whenever you add this, so it doesn’t have a big jump on the first entry.
Then I just added it directly as a type of grid consumption with a fixed price set to 1000x my real daily supply charge:
This only adds 1W of “fake” usage and will update daily without any automation or need for a utility meter entity.
With total_increasing, I think it could even work to just have a sensor which toggled between 0 and 1 every 12 hours as the 0 will be interpreted as a start of new cycle, but I haven’t tested that.
Just wanted to say thanks for this, been trying unsuccessfully to use other methods but this is quick, easy and reliable. Cheers!
Hi Bo,
thanks for sharing your solution. i went with yours, however my daily supply charge does not increase by the hour. It froze on 0,001 kWh. Besides changing the ID and the date, i did not change your code. Date & Time sensors are added to the config. No errors in the log.
Any idea whats wrong here? thanks
edit. sorry maybe i am confused. This counter should be increased each day or each hour? i thought it would be each hour but then it wouldn’t show due to decimal numbers i guess.
I thought that this was the issue but i think 0,001 kWh is indeed correct as only one day has passed. Though, my energy meter neither shows cosumption nor price for that entity.
Somethings strange here 
Same here, but I assumed that it would stay at 0.001kWh every day and multiply by the fixed cost * 1000
But I get zero in my cost
Same issue here:
zero cost showing in the energy sources page
Daily supply charge 0 kWh €0.00
And the entity has got a value of 0.001
Daily supply charge - 18 hours ago - 0.001 kWh
Any ideas?
hm it’s kinda strange. I now checked on it again. it jumped from 0,001 to 0,002 at 2 PM local time. Though i have to admit i fiddled around with it and set the starting date to 2022-09-28. I initially deployed it however around 12 AM, at least thats when it started to tick to 0,001.
So as for now, it seems that it started ticking on its first regular basis on 2 PM. It produces a single bar in the engergy meter and i am not sure if thats now for the whole day, or only for 1 hour. If it’s meant to be for the whole day, then the costs would be incorrect.
I am a bit confused to be perfectly honest.
The increment is once per day so you need to adjust your price to reflect that.
I’ll report back tomorrow when i get to 0.002.
oh damn. I miscalculated my total supply charge when recalculating the other way around. It’s works out perfectly for me!
So two questions remain for me:
generally, i think this should be implemented by the hass team natively by now. i have not heard of a single energy bill which has no basic charge, supply charge, service charge or network fees.
thanks all for now !
Hi all. In theory, you could have calculate the number of hours instead of days between now and the starting date, but then you’ll have to make sure the price you give the entity also adjusts it by a factor of 24.
Personally, I don’t think this makes sense to do as it’s not what the energy retailer does (at least not the ones I’m familiar with).
I also had mine update around 2pm and I don’t know why that is. It might be something to do with when the HA energy dashboard does statistics calculations or it might be something to do with time zones perhaps. I haven’t looked into it because all I really cared about is that it increments by my supply charge once within a 24 hour window and that I have the statistics over the longer term.
alright, thanks to you
I’m going to test a version of this where the value template is just:
{%- if now().hour < 12 -%}
0.001
{%- else -%}
0
{%- endif -%}
In the morning, this will register 1W and in the afternoon 0W. This should work because of state_class: total_increasing which, according to these docs carry the semantics of:
A decreasing value is interpreted as the start of a new meter cycle or the replacement of the meter.
If this works, then it will mean there is no need to customise the template for each time it is set-up by a new person.
Still no luck for me…
The energy consumption is increasing correctly (now on 2W on day 2, but this isn’t translating into a cost on the dashboard)
What price did you give the entity when you added it to the energy dashboard? Did you multiply it by 1000 as per my instructions?
If your daily supply charge were £1/kWh, then this would only be 0.2p so far. You’d have to add this entity at £1000/kWh, since we are only incrementing a single watt per day with this approach.
Thanks bo. Yes I did set that correctly I set it to 330 as my daily supply charge is £0.33
However this morning it has started working, so I think it just needs a little while to kick in. And perhaps I was fiddling around with too many settings trying to get it to work.
Great solution thanks!
Good solution. I went with your method and it is working fine for me. Thank you for sharing it
